This invention relates to harvester threshers.

and more particularly it relates to harvester threshers of the self-propelled type.

In this type of harvester thresher. a source of power is supplied on the harvester thresher which drives the various parts of the harvester thresher and also propels the harvester thresher over the ground. In a self-propelled type of harvester thresher. it is essential that the framework of the machine be constructed so as to support the separator, platform, grain tank, 'and motor of the harvester. Since the harvester thresher is self-propelled, a suitable transmission must be providedwhereby the speed of the harvester thresher may be controlled, and it is also desirable that the drives to the various parts of the machine be assimple as possible.

It is, therefore, an important object of the present invention to provide an improved selfpropelled harvester thresher.

Another object of the invention is to provide an improved frame structure for supporting the self-propelled type of harvester thresher.

Another object of the invention is to provide a novel means for driving the various parts of the harvester thresher.

Another object of the invention is to provide a novel drive from the motor yto the cylinder and` structural embodiment taken in conjunction with the accompanying drawings. f
